Psalm 127:1-3

King James Version

127 Except the Lord build the house, they labour in vain that build it: except the Lord keep the city, the watchman waketh but in vain.

² It is vain for you to rise up early, to sit up late, to eat the bread of sorrows: for so he giveth his beloved sleep.

³ Lo, children are an heritage of the Lord: and the fruit of the womb is his reward.
